application filed (lctoher 25, 1915.

To all whom it may concern:

Be it known that I, Anonrn C; Rncnnn, a citizen of the United States,residing at @akville in the county of Litchlield and State ofConnecticut, have invented a new and useful improvement in PortableElectric Lamps; and I do hereby declare the following when taken inconnection with the accompanying drawings and the characters ofreference -arked thereon, to be a full, clear. and description of thesame, and which said orawinp's constitute part of this applicatiom andrepresent, in

igure 1 is a. side view of a portable electric lamp constructed inaccordance with my invention. Fig. 2 a top or plan view of the same. Fig3 an underside view on an enlarged scale. a broken transverse sectionalview showing the parts in the open position. Fig. 5 a similar viewshowing the parts in the closed position.

This invention relates to an improvement in portable electric lamps, andparticularly to portable electric lamps which areot' the so calledcandle type, for the reason that the holder is inthe "form of acandlestick.

The object oi this invention is to provide simple means for opening andclosing the circuit through the lamp. and the invention consists in theconstruction hereinafter described and particularly recited in theclaims.

In carrying out my invention I employ base 2 struck up from sheet metaland provided with a handle 3 formed with a slot i for the purpose aswill hereinafter appear. Mounted on the base is a cup within which is asocket 6 which receives the lower end of a battery container 7, this container preferably being in imitation of a candle and carries anincandescent bulb S at its upper end. This container receives the. usualbattery 9 the lower end of which is exposed through openings 10 formedin the base, cup, and socket. Pivotally mounted in the base is acontactlever 11 the inner end 12 of which is in line with the exposed end ofthe battery 9, and the other end is pivotally connected ith thelinger-piece 14: which is provided with a pin 15 adapted to engage withthe upper end of the slot l through which the finger-piece extends. Alsomounted in the base is a. spring 16 which "J w Ba tel Serial No. 57,652.

bears upon the contact lever 11 near its inner end, the tendency oi? thespring being to move the end 12 out of contact with the hattery. and tolift the linger-piece away from the handle which is the open position ofthe lamp, as shown in Fig. i. To close the circuit throughthe lamp oirtolight the lamp. the finger-piece 1% will be moved downward slightly orpressed against the handle which forces it downward so that the pin 15enters the slot at and engages with the upper end thereof as shownil'nlfii oi the drawings. This downward movement of the finger-piecelifts the inner end 12 of the contact lever ll and forces it intoengagement with the lower end of the battery as also shown in Fig. 5 ofthe drawings. so as to close the circuit through the lamp. It will beunderstood that one pole ofthe lamp is connected with the battery andthe other through the container 7 with the base, and so that when thecontact lever touches the battery the circuit is closed.

To open the circuit it is only necessary to move the linger-piece awayfrom the handle which can readily be done by a slight move ment of thethumb or one ling; r so as to move the pin 15 out of the slot i andallow the spring 12 to act to move the inner end of the contact leverout of engagement with the battery and at the same time lift thefinger-piece away from the handle. This device provides simple means bywhich a portable electric light of the candlestick time may be readilyoperated by the thumb or one finger.

I claim 1. A portable electric lamp comprising; a hase. socket andcontainer. said base provided with an upwardly projecting handle saidhandle formed with a slot. a. contact lever pivoted in the base, afinger-piece fivotally connected with the outer end of said lever andprojecting}; upward through said slot in the handle and provided with apin adapted to engage with the upper end of said slot.

2. A portable electric lamp comprising a base provided with a handleformed with a slot, av socket mounted on said base. a container adaptedto be mounted in said socket said containerprovided at its upper endwith an incandescent bulb, an opening through the top of the base andsaid socket, a battery pivotaliy connected with the upper end of cell insaid container the bottom of the batsaid lever and projecting upwardthrough tery heingexposed through the opening in said base, a slet 1nsaid handle, said finger- 10 the top of the base, an operating leverpivotpiece provided Witha pin adapted to engage ally mounted in the baseand having its 1nwith the upper end of said slot.

ner end in line with said opening, aspring bearing on saidcontact-lever, a finger-piece ADOLPH O. BECKER
